Abstract

PURPOSE:To implement a loopback test of all time division multiplexers individually by generating a timing corresponding to a location of a control path assigned on a transmission line, inserting a control signal to the location of the allocated control path and looping back a data to a controller. CONSTITUTION:A time division multiplexer at a receiver side uses an interface section 42 to convert a transmission line interface, a drop section 34 extracts a control signal and it is sent to a communication control section 22. When the content of control represents a loopback instruction, the data is outputted to a loopback section 5 to execute the loopback test of the data. A timing generating section 6 generates a timing corresponding to the position of the control path allocated in the loopback data. A control signal insertion section 7 inserts a control signal from the communication control section 22 to the position of the control path allocated on the transmission line in matching with the timing. Thus, even when the data is looped back, the control signal is not looped back.

In this way, in the conventional example, there is no prevention of loopback, so if the transmission line on which control signals are multiplexed is looped back for testing, the control signal sent by the control device may be folded back to the control device. I'll return it. Therefore, communication between the control device and all time division multiplexing devices becomes impossible,
The drawback was that it was not possible to manage and control the time division multiplexing equipment.
